I need some help. A client of mine had his iMac stolen. He has one of those tracing softwares installed on it...I am not sure but I think its either undercover or lojack. Is there anyway that the perp who stole it can wipe the computer clean where these softwares will be deleted, or do they installed even after the hard drive gets wiped? He said he tried activating his undercover but it is not showing that his computer has been online. I am not sure about all this since the only Apple product I have is an iPhone :-( Please Help.
